Answer: X - 5 ÷ 15
Step-by-step explanation: The first step to algebra is to collect like terms. Since X is an a variable, we cannot solve X - 5. But we can solve 5 + 10, since those are both numbers. 5 + 10 is 15. So therefore, your simplified expression would be X -5 ÷ 15.

enice brudley purchased 3,000 shares of GTI petroleum at $6.30 per share. The broker's commission was $19.95 for fewer than 1,000 shares or $0.02 per share for 1,000 or more. What was the cost of the stock? What was the total paid?
Answer:
Step-by-step explanation:
Cost of stock (without the broker's fee) : 3000 * 6.30 = 18,900
Cost of broker's fee: 3000 * 0.02 = $ 60
For a total cost of (18,900 + 60) = $18,960
Answer:
1. Cost of stock = $ 18,900
2. Total paid = $ 18,960
Step-by-step explanation:
1. Let's review the information provided to us to answer the questions correctly:
Number of GTI petroleum shares purchased by Enice = 3,000
Cost per share = $ 6.30
Broker's commission was $19.95 for fewer than 1,000 shares or $0.02 per share for 1,000 or more
2. What was the cost of the stock? What was the total paid?
Let's calculate the cost of the stock, this way:
Cost of stock = 3,000 * 6.30
Cost of stock = $ 18,900
Cost of brokers' commission = 3,000 * 0.02
Cost of brokers' commission = $ 60
Total paid = Cost of stock + Cost of broker's commission
Total paid = 18,900 + 60
Total paid = $ 18,960

the length of a rectangle is 8 feet more its width.the area of the rectangle is 84 square feet find its length and width
Answer:
length=8+w........1
area=84square feet........2
area of rectangle =length x width
area=(8+w)x W
area=8w+w^2
84=8w+w^2
w^2+8w+(4^2)=84+(4^2)
(w+4)^2=84+16
(w+4)^2=100
√(w+4)^2=√100
w+4=±100
w+4=100 or w+4=-100
w=96 or w=-104
the answer is 96
Which ordered pair (x,y) makes this relation a function?
{(2,3), (–2,5), (4,4), (-4,5), (x,y)}
A. (-4, -1)
B. (-1,-1)
C. (-2,-1)
D. (2, -1)
Answer:
Step-by-step explanation:
A i think sorry if it is wrong
The only ordered pair that can be added to make the relation a function, without repeating an x-value, is option B. (-1,-1).
The question is asking which ordered pair (x,y) makes the given set of ordered pairs a function. A function is defined as a relation where every x-value (input) is associated with exactly one y-value (output). We already have the points (2,3), (–2,5), (4,4), and (-4,5) in our set. To maintain the definition of a function, the x-value of the ordered pair we are going to add cannot be the same as any x-value already present in the set. Looking at our options:
A. (-4, -1) - This would not work because the x-value -4 is already paired with the y-value 5 in our set.B. (-1,-1) - This is a possibility as the x-value -1 is not in the set.C. (-2,-1) - This would not work because the x-value -2 is already paired with the y-value 5 in our set.D. (2, -1) - This would not work because the x-value 2 is already paired with the y-value 3 in our set.Therefore, the only ordered pair that makes the relation a function is option B. (-1,-1).

Determine what each parameter in the function represents.
A) The 75 is the initial number of cells, and the 2 indicates that the number of cells doubles every minute.
B) The 75 is the initial number of cells, and the 2 indicates that the number of cells increases by 2 every minute.
C) The 75 is the number of cells at 1 minute, and the 2 indicates that the number of cells doubles every minute.
D) The 75 is the number of cells at 1 minute, and the 2 indicates that the number of cells increases by 2 every minute.
Answer:
A) The 75 is the initial number of cells, and the 2 indicates that the number of cells doubles every minute.
Step-by-step explanation:
The function for cell duplication where the cells duplicate every minute, is given by [tex]f(x)=75(2)^x[/tex]
The initial number of cells occurs when x=0:
[tex]f(0)=75(2)^0[/tex]
Note that every non-zero number to the exponent of zero is 1.
[tex]\implies f(0)=75(1)=75[/tex]Therefore the initial number of cells is 75
The two is the multiplicative rate of change, therefore the 2 indicates that the number of cells doubles every minute.

Let the population of a city be 1,006,150 people. What is the least number of people that share a birthday?
Answer:
The least number of people that share a birthday is 1, no matter what the size of the population is.
Step-by-step explanation:
Tricky Question
Suppose there is one person that has their birthday on Feb 02. It's perfectly possible that no one else in the city has their birthday on the same day, i.e. their birthdays are any time except Feb 02. So that person will be the only one who has that as a birthday. It's even possible that no one has a birthday on Feb 02, so the answer will be zero, but it's not possible to talk about sharing if no one is doing it, so the answer is
The least number of people that share a birthday is 1, no matter what the size of the population is.
Note: If this question is talking about probability calculations, then the matter is totally different.

suppose that the water level of a river is 34 feet and that it is receding at a rate of 0.5 foot per day. Write an equation for the water level ,L ,after D days . In how any days will the water level be 26 feet
Equation: L= -0.5D+34.
The water level be 26 feet in 16 days.
Step-by-step explanation:
Let us consider the initial level (x=0) of the water is 34 feet. Then its coordinate point can be written as (0,34).
The water is receding at the rate 0.5 feet per day, which given us the information that 0.5 is the slope since it is the rate of change and it is decreasing so it is a negative slope.
⇒m= -0.5.
The line equation is y = mx+c. Let us rewrite as L= mD+c.
Where L is the level of water(y-axis) and D is the days(x-axis) and c is y-intercept.
⇒L= (-0.5)D+c.
To find y-intercept, substitute (0,34) (the known point from the graph) in the equation. Also, the point in y axis when x=0 is y-intercept.
34= (-0.5)(0)+c.
c=34.
∴L= (-0.5)D+34.
To find the days when the water achieves level as 26 feet:
26 = (-0.5)D+34.
26-34= (-0.5)D.
-8 = (-0.5)D.
D= [tex]\frac{-8}{-0.5}[/tex].
D= 16.

a (3,−2)
b (−3,2)

Together, teammates Pedro and Ricky got 2687 base hits last season. Pedro had 283 more hits than Ricky. How many hits did each player have?
Answer:
Ricky hits 1202 base
Pedro hits = 1485 base
Step-by-step explanation:
Pedro + Ricky = 2687 hits
Let Ricky hits = x
So the Pedro hits will be = x + 283
( x + 283 ) + x = 2687
2 x + 283 = 2687
2 x = 2687 - 283
2 x = 2404
x = 1202
So the Ricky hits 1202 base
Pedro hits (1202 + 283) = 1485 base
Final answer:
To determine the number of hits Ricky and Pedro had, a system of equations was set up and solved. Ricky had 1202 hits, while Pedro had 1485 hits last season.
Explanation:
To solve the problem involving teammates Pedro and Ricky's base hits, we need to set up a system of equations based on the information given:
Pedro and Ricky's hits together total 2687.
Pedro had 283 more hits than Ricky.
Let's denote Ricky's hits as R and Pedro's hits as P. The two equations representing the situation are:
R + P = 2687
P = R + 283
To find the number of hits Ricky had, we can substitute the second equation into the first:
R + (R + 283) = 2687
2R + 283 = 2687
2R = 2687 - 283
2R = 2404
R = 2404 / 2
R = 1202
Now that we have Ricky's hits, we can find Pedro's hits by adding 283 to Ricky's total:
P = R + 283
P = 1202 + 283
P = 1485
Therefore, Ricky had 1202 hits, and Pedro had 1485 hits last season.
